Operation
english
To adjust the wheel, loosen the locking screw
(Fig N/1) and turn the wheel centre clockwise
or counter clockwise to the desired position
(Fig N/2), and lock the wheel again (Fig N/3).
If the blade has wandered too much to the
left, adjust wheel centre clockwise (- sign). If
the misalignment is to the right, adjust counter
clockwise (+ sign). The extent of the adjustment
depends on the actual misalignment.
Remember to lubricate the adjusting wheel at
regular intervals.
Installing and changing
the saw blade
WARNING: To reduce the risk of injury,
turn unit off and disconnect it from
power source before installing and
removing accessories, before adjusting or
when making repairs. An accidental start-up
can cause injury.
Remove the power plug from the socket.
Check that the motor unit is locked in the upper
position.
Remove the blade guard cover (Fig. O/1) by
opening the screw (Fig. O/2). Press the spindle-
lock button (Fig. A/13) and simultaneously rotate
the blade by hand until the spindle-lock button
drops a further distance of about 7 mm. Now
the rotation of the blade is prevented. Use the
blade key to open the blade attachment bolt.
Remove the securing bolt (Fig. O/3), the washer
(Fig. O/4), the blade fl ange disc (Fig. O/5), and
the blade (Fig. O/6).
Before installing a new blade, check that both
blade fl ange discs are clean. Place a new
or sharpened blade on the back fl ange disc
(Fig. O/7), so that the marked side of the blade
is facing outwards and the arrows on the blade
are facing in the same direction as the rotation
direction markings on the inside of the blade case.
Ensure that the new blade goes right to the bottom
in the back fl ange disc. Put the blade fl ange disc,
the washer, and the securing bolt back in place.
Press the spindle lock button and tighten the blade
securing bolt. Put the blade guard cover back in
place and tighten the fi nger bolts.
